Solving Systems of Equations: Substitution and Elimination Notes
A guided-notes packet for 8th graders that walks step by step through solving systems of linear equations by substitution and elimination, using the same system to compare the two methods side by side. It builds algebraic manipulation skills and the habit of checking that an ordered pair satisfies both equations, with fill-in-the-blank steps that keep students actively engaged during a lesson.

Teacher Guide & Tips
- Use this as a 45-minute whole-class notes session when introducing or reviewing systems of equations, projecting the table and having students fill in each blank as you work the example together.
- Discussion question: When would you choose substitution over elimination, and what features of a system make one method faster?
- Scaffold for struggling readers: pause after each step to have students restate the goal of that step in their own words, and provide a worked model for one additional system before they attempt independent practice.
- Extension for advanced students: have them find a system where neither method is clearly more efficient, or explain why a system with no solution or infinitely many solutions behaves differently under each method.
- Estimated time: about 20 minutes to complete the notes with the class and another 10 minutes for a quick check-for-understanding problem.
